KSB Launched Submersible Borehole Pump Series
KSB launched the UPA 100 C series to be used in water supply, irrigation, lowering of ground water levels, pressure boosting and fire protection.

The maximum discharge head is 400 metres and the maximum flow rate 15,000 litres per hour. The temperature of the fluid pumped can be up to 30 °C.
All components are made of stainless steel. The pump units are of a very robust design and capable of handling water with a solids content of 50 grams per cubic metre. The minimum thickness of the stainless steel walls is 1 mm. An integrated, hydraulically optimized anti-blockage design check valve prevents the discharge pipe from emptying when the pump unit is switched off. This ensures that the pump is not damaged as a result of reverse rotation.
The canned motors are available in single-phase AC (0.37 - 2.2 kW) and three-phase (0.37 -7.5 kW) design. Generously dimensioned intermediate bearings at each pump stage prevent potential shaft misalignment. Their special design allows optimum lubrication of the bearing faces.
Its simple configuration makes the pump set very service-friendly. Casing wear rings and bearings can easily be replaced by new parts. Thanks to the fine-tuned range of motor sizes, the user can choose the optimum drive rating to match any application. Couplings and drive flanges have mating dimensions to NEMA standards.
